GEORGE OHAPPEL, OF BROOKLYN, NEW YORK.

LAMP.

SPECIFICATION forming part of Letters Patent No. 247,307, dated September 20, 1881.

Application filed March 30, 1881. (No model.)

To all whom it may concern Be it known that I, GEORGE OHAPPEL, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Lamps, of which the following is a specification.

The object of my invention is to provide a simple and simply-constructed lamp in which chimney and a flat wick in connection with a flat chimney, although the round wick-tube and wick were far more expensive than the fiat ones, so, also, the flat chimney more expensive than the round one.

In the accompanying drawings, Figure lrepresents a vertical section of my improved lamp, corresponding to the section-line :10 00 of Fig.2. Fig. 2 is a plan or top view of the burner. Fig. 3 is a vertical section of the burner, taken on the line y y of Fig. 2, and seen in the direction of the arrow.

Similar letters of reference indicate like parts in the several figures.

A is the oil-receptacle of thelamp. B isthe cover threaded to the same, and provided through its center with aflat tube, 0, forholdin g a flat wick, a. The tube 0 has two vertical slots, 0, through one of its sides, through which access is gained to adjust the height of the wick.

To'the cover B, at opposite edges of the tube 0, are soldered two vertical metal strips, 1), whose upper ends are bent outward and end with horizontal flanges upon which the gallery or chimney-holder D is secured by rivets d, as shown in the drawings.

E is a round tubular glass chimney having an outwardly-flaring flange or annular lip, e, at its base, as shown.

The chimney-holder or gallery D consists of a circular plate having formed upon it at its periphery avertical annular flange, F, to which is secured a small tube or hnb, f, threaded to receive a small horizontal thumb-screw, G.

On the side of the flange F diametrically opposite to the screw Gr are formed, by slitting the flange at suitable places and distances apart, two little tongues, f, which are then bent inward, (see Fig. 2,) and when the chimney is placed upon the gallery D, as in Fig. 1, they serve as catches above the annular lip e to prevent the latter from being raised on that side, while the screw G, turned inward above thelip eat the opposite side, serves for the same purpose and also for preventing the lip e from getting laterally out from under the catches f,

thus retaining the chimney firmly upon the holder D.

The plate D has no perforation,-excepta central opening, H, formed by making a slit (longer than thewidth of the wick) longitudinally above the wick-tube O and short crossslits at the ends of the central slit, then bending up the free cut edges of the two lips h, thus formed into an inclined position, converging upward equally toward the center line of the wick, as shown in Figs. 1 and 2. Itis evi- (lent that by having thus only one opening in the plate D, converging centrally toward the wick a, the draft is also centralized and intensified at the point of combustion.

In order to insure a snfficient quantity and uniform flow of air to the central opening, H, unimpeded by incidental side drafts, I secure to the under side of the plate D, between the supports 1), a preferably cup-shaped plate, I, provided with anumber of small uniformly-distributed perforations, as shown in the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the flat wick-tube O, the gallery D, supported to surround the upper end of the said tube, and having but one (a central) opening converging toward the point of combustion, substantially as and for the purpose set forth.

2. In combination with the wick-tubeO, the gallery D, consisting of a solid plate having a toward the saidtube, substantially as specified. pose set forth.-

3. In combination with the flat tube (J, and 'GEO. GHAPPEL. 5 with the closed gallery D, having but one cen- Witnesses tral opening, H, about the upper end of the JOHN M. STELLE,

central opening, H, formed by slitting the plate, subjaoent to the said gallery and surrounding as described, and bending up lips h, converging the said tube, substantially as and for the purtube 0, the perforated draft-plate I, arranged ALEX. F. ROBERTS.
